Five guides for the moments when a document is too sensitive to hand to a server.

The thread through every guide: the work happens on your device, not on ours.
Load the page, then turn on Airplane Mode and run any tool. It still works, because your file was never going anywhere in the first place.
With the network on, you will see small first-party pings for the daily quota and our analytics, never your file, and no third-party trackers. That is the honest version of "private": the document itself is never part of a single request.
